' Threading Tape into Edgings, of which the following is aspeciication.

The principal objects of myinvention are rst, to providein a machineforinsertingtape in lace or edgings a star-wheel'the star-likeprojectionsv4 of which en gage each alternate bar of the laceor edging'to-raise anddelive'r the barfupon a 'needle andrtoppermitpassing of asucceeding bar under theneedle to interlace the body of the needle intothe lace v or edging as the same is advanced upon the needle; second, toactuate the star-wheel by each alternate bar of the lace or edging topermit .the proper insertion of the needle under and over the barsindependent of the varying or unequal distance of the bars from.

each other, and, third, to provide in such a ymachine a groovedtape-baradapted to receive and'hold'the tape and to be readily engaged andclampedas well as disengaged from the needle.l A n l The nature andscope of my invention will be more fully understood'froin the followingdescription, taken in connection with the accompanying drawings,fo'rming'part hereof, in whiehr- Figure lis a'longitudin'al sectionalIview of a machine embodying main features 'of my invention.

sion-rollers for the lace or edging. Fig. 4. is

a top or plan viewof Fig. 3. Fig. 5 is an enlarged detail viewillustrating a portion of the needle rand tape-bar and the tape insertedinto the bar; and Fig. 6 is a side elevational view` of Fig. 5,partially sectioned, illustrating the-mode of uniting the tape-bar withthe Y A needle-body and clamping the end of the tape My invention hasrelation to that class ofl between the said bar and body.

Referring to the drawings, inthe machine as illustrated the lace oredging ct is univound from a reel ct and passes under a guide a2 andflattening and friction rollers a3 and a4 vto stretch the lace or edginglaterally and to maintain its bars a5 in a flat or straight conditionbefore presenting the same to a table h. 'To the under face of the tableb is secured a guide b', which is adapted to engage the barswa` of theedging and to guide the same to two upwardly-projecting and curvedguide-fingers 'b2 and b3, between which a star-wheel C is adapted torotate. The table bis 'furthermore provided with a springarmlii, thecurvedend hof which is centrallyilocated between the guide fingers b2and h3 and which is adapted to depress the tape a between said bars a5of the fingers for a purpose to be presently more fully explained. Thestar-wheel C is loosely mount.- ed on a shaft o', secured to a standardc2 and held in frictional contact with the same by a spring c3, mountedon the shaft c, as illustrated in Figs. V3 and 4. The star-likeprojections cf of the star-wheel rotatebetween f the curvedguide-lingers b2 and b3 and between which the curved delivery end d ofthe threading-needle D is located, so as to permit the free rot-ation ofsaid wheel andits projections.

tal position by milled feed-rollers e, e', e2, e3, e4, and c5, whichalso engage'theedging a and y-rintheirrotation` feed the edging forwardfrom left to right of the machine. In orderto insure lthe proper andalternate presentation of the bars a5 of the edging ot to the star-wheelC, the bars a5 in the forward travel of the lace or edging beneath thetable b areu first The threading-needle D is held in a horizon- ICOasbetween the star projectionsc4 of the starwlleel C, which projections,however, are only permitted to engage the bars a5 after the same havetraveled over the forward portion of the guide-fingers b2 and b3, asillustrated in Fig. 3. The free ends of the guide-fingers are depressed,permitting the star projections to project above the fingers in suchmanner that a forward sliding bar will first engage the straight portionci of the notched end of the projection c4 until it is prevented fromfurther movement thereon b v abutting against the linger c6 of thenotched end. The bar a in its forward movement will now rotate thestar-wheel C until the projection cV1 has delivered the bar a5 of theedging a upon the downwardly-projecting end d. ofthe needle D and untilthe fingers c of the projections c4 are disengaged from the bar a5 bythe bar a5 sliding forward on the needle D, at which time the star-wheelC comes to a standstill. The next succeeding bar a5 of the edging,however, will not be engaged by a star projection c4 of the star-wheelC, since the distance of the projections c4 from each other is greaterthan the distance of the bars a5 of the edging a from each other. Thesucceeding bar a5, fol lowing the bar raised by the star projection e4,will slide forward over the fingers b2 and and b3, and the end b5 of thetension-arm h4 by depressing the bar a5 will conduct the same under theend d of the needle D and in this manner interlace the needle D into thelace or edging. The star-Wheel being rotated by the bar a5 of the laceor edging a, which has been deposited upon the needle D, brings anotherof the star projections c4 in such a position that a bar a5, followingthe bar fed under the needle D, will engage the projec- Lion c4 androtate the wheel C, as herinbefore described. In other words, eachalternate bar a5 of the edging a will be engaged b v a star projectionc4 of the star-wheel C and placed upon the needle D. The rotation of thestar-wheel C by alternate bars of the lace or edging avoids thenecessity of having the bars a5 arranged a predetermined'distance apartfrom each other, since the proper operation of the star-wheel is madeentirely independent of location and distance of the bars a5 from eachother. It therefore follows that the proper interlacing of thethreadingneedle D into the edging will in all instances be accomplishedwhether the bars a5 of the edging follow each other in regular orirregular sequence. The lace or edging delivered upon the needle D isfed over the body of the same by the milled rollers e e', e2 and e3, ande4 and e5 and onto a grooved bar l, adapted to receive the tape f to beinserted into the edging. In order to connect the grooved bar E with theneedle D, the same is provided with a contracted extension d2 of suchshape that when the extension is inserted into the grooved bar the sidesand upper and under face of the needle-body will be in alinement withthe grooved barE, as illustrated in Figs.

5 and 6. The end of the tapef is at the same time securely clampedbetween the extension (Z2 of the needle D and the grooved bar E byplacing the tape around the edge of the grooved bar, which slides underthe extension d2 and between thc same and a leaf-spring d3,

preferably integral with the needle D. The' leaf-spring d3 furthermoreholds the grooved bar E in engagement with the extension cl2 of theneedle D and at the same time adords means of ready connection anddisconnection of the needle to and from the grooved bar E. The groove ein the bar E is of sufficient depth to prevent the contacting of thebars a5 of the lace or edging a with the tapef during the feeding of thebars aGover the grooved bar E. To maintain the body of the needle D andthe grooved bar E firmly in position in the machine during interlacingof the needle into the edging and during'feeding of the same over theneedle andthe grooved bar, the first two sets of milled feed-rollers ee' and e2 e3 are grooved to receive the contracted body of the needle D,whereas the last set of milled rollers e4 and e5 is channeled toaccommodate the flat grooved bar E. The tension exerted upon the lace oredging ot by the tensionrollers (t3 and a4 and the milled rollers c e',c2 e3, and e4 and e5 is sufficient to hold the edging a with therequired amount of friction down upon the curved guide-fingers b2 and b3and to maintain the same also in a dat condition. After all the lace oredging has thus been placed upon the grooved bar E the needle iswithdrawn from the bar-and the edging removed from the bar, during whichmanipu-v lation the tape f is properly inserted in the edging in theusual and well-known manner.

Having thus described the nature and objects of my invention, what Iclaim as new, and desire to secure by Letters Patent, is-

l. In a machine for threading tape into lace or edging, a wheel havingradial projections, the peripheral face of said projections having astraight portion terminating in a finger, all arranged so that thedistance between successive bars of the lace or edging to be fed isless4 than the distance between successive projections on said wheel.
